On kernel-less clique-acyclic orientations of minimally imperfect graphs

, 2001
In this paper we will show some properties of the kernel-less clique-acyclic orientations of minimally imperfect graphs and discuss some relation between these properties, Berge and Duchet's Conjecture about kernel-solvability and the Strong Perfect ...
